This new method which is worked out in Isfahan University of Technology, makes it possible to analyze the phases quantitatively in minerals and powdered materials by X Ray Diffraction and without any reference material. To identify n unknown phases, n different combinations of phases, from fine and coarse fractions, or etc., must be obtained. Amorphous phases should not exist. Intensity ratios ...

Microencapsulation has become a common technique in the production of controlled release dosage forms. Many results have been reported, concerning the use of alginate beads as controlled release drug formulations. Alginate has a unique gel-forming property in the presence of multivalent cations, in an aqueous medium. Ibuprofen is an excellent analgesic and antipyretic, non-steroidal anti-inflam...

This research focuses on reconstructing migration and dietary strategies of individuals in the Iron Age. Elemental analyses from archaeological skeletal remains yield an important perspective on temporal shifts in diet in relation to social and environmental circumstances. The elemental ratio data such as dietary and environmental changes have shed light on crucial issues in archaeology. The ce...
